4. The MYP type cable consists of 3 main cores with insulation and shielding, and a grounding wire covered with a semi-conductive rubber layer. The cores are twisted around a semi-conductive rubber layer pad to form the cable. It is sheathed with a black chlorinated polyethylene rubber jacket or a thicker black chloroprene rubber jacket for added safety, provided by the manufacturer.
5. Conductor Core: Made of soft copper wire, its performance meets GB/T3956-1997.
6. Insulation: Utilizes XJ-00A type rubber as specified in GB7594.2-1987.
7. Wire Core Identification: Insulated color-coded identification, with the main cores being red, green, and white.
8. Ground Wire: Semi-conductive rubber sheathed.
9. Insulation Shielding: Wrap semi-conductive tape over the insulated surface.
10. Cable assembly: Consists of 3 main cores and 1 ground wire wrapped around a semi-conductive rubber core, twisted together in a clockwise direction.
11. Sheath: Made of XH-03A rubber as specified in GB7594.7-1987. The oxygen index of the sheath rubber is ≥40.
12. The flame-retardant performance of finished cables meets the requirements of MT386-1995.
13. Cable Markings: The cable surface is imprinted with model, voltage, specifications, and manufacturer.
